STITCH: PICK. 7

' Application inear p'ruar 14-, 1927,. senai No. 167,996;

the like where it is desired to have the same withdrawn. for re-stitching, or otherwise; that will be strong,rdurable, cheap, easily applied, easily reversed, cheap y manufactured; more efiective indigging, out the stitches, and more economical in. applyingandinoperation. I V 1 7. Other objectsand the novel features of the invention will appear from the specification, claim and drawing,ofwhich drawing, Figure 1is a front elevationof the device show ng.set-screws, end ofshaft and cap- 20 screwrdotted-in, Fig.2 is'a sectional view of the body-of the device; Fig. 3 is an, end view of-the device; Fig. 4 is a perspective view of the cutteror pick of the device.

Like characters of reference designate like parts in all the figures.

. In such work as half-soling. shoes, and the I like, after the; original sole has been sewed on and isworn ofi, or'the. shoehas to be half soled over the old stitches, when completed the half-soling: work leavesthe extended edges of the upper partofvthe sole filled 'withva part of the old stitches, if not all of them ,.making. the ob look bad and the rough ends of man ofthe oldstitches where L split or broken stlcking out in plain view. WVith the use of the present device the old stitches are :all. dugout and removed and the new stitches on the new half-sole are madein the oldholes formerly filled by the old threads or stitches. The result is the job looks neat and trim, and has every appearance of a new sole, lasts longer and lengthens the life of the use of the shoe, and adds to the pleasure of the wearer of the shoe.

To accomplish the result desired, and as a one embodiment of my invention, I provide a claw-toothed wheel member 1 having a square central opening 2 for anchoring the claw-toothed wheel 1 firmly in place. The wheel has a plurality of claw teeth 3, each having a straight front edge 4, an outer straig'ht'cutting edge 5 and corners thereto 6,

7 The wheel is made sufficiently thick to 55. provide strength or the work'required of said teeth. Frem the bottom 8 of the frsint withthe shaft 25. Said shaft as straight edge f said teeth it-o the bottom 9 of the curved back 10 is a rounded surface 11 on the periphery of said wheel exclusive of its'teeth. ,Between the cutting or picking edges 5, 6, 7, of said teeth and the curved back. 10 is a beveled straight surface 12 ending at 13, 14. g g

I also provide as a means for holding and operating said wheel member 1 a bottle shaped body member 15 having shoulders 16 and neck 17, an opening in its central bottom portion 18 extending to its inner top 19; two opposite threaded apertures'2l'l. 20', through its outer walls are adapted to receive therein two threaded set-screws 21, 22',

having kerfs 23, 24, cross sectioning their outer ends to ass stf in tighteningsaid set I screws to securely hold said body 15 on a shaft 25 extending in said opening 18 to approximately 26. On the upper part of the neclrand surrounding said neck portion 17 of said body 15 is a flange 27 extending ,outwardly from said neck and forming a shoulder therebelow. The upper outer surface of saidflange 271is slightly beveledand the surface thereabove has a square shaped upstanding central shoulder 29 with straight surfaces, which is adapted to receive' and hold the square shaped central opening 2 of said clawjshaped wheel member 1, or be surrounded thereby. In the center of said square shaped shoulder 29 is a round lip-standing portion 30 having an outer edge Sland inthe center of which round portion 30'is an inwardly extending threaded bore 32, and'the said claw toothed wheel' member 1 isfastened to said square shoulder 29 by fitting the'square opening 2 in said wheel 1 therearound. I also provide a guard 33 with an outer periphery 34:, said guard fitting over said wheel member 1. The outer cutting edges 5 of the teeth 3 extend a short distance beyond the periphery of the guard. Said guard has in its center a perforation 35 adapted to fit around said upstanding round portion 30. It is to be understood that the guard is not so connected as to compel it to revolve with the other partsof the device but may do so. Over the whole device as described is a threaded cap-screw 36 with a bevel topped head 36*,threaded bolt portion 37 and a kerf 38 in the top head. Said cap-screw is screwed into the threaded bore 32 securely holding the wheel 1 and the body 15 rigidly together and revo referred to means the end of a shaft forinii'ig' a part of a finishing machine for the making and mending of shoes, and the like, and presupposed to be attached to a means of power for the running of the shaft which means of power is not shown herein and is not claimed as a part of this invention. Sutii cieut space is provided between the guard 33 and cap-screw 36 and sutiicient space between the guard 33 and the wheel 1 to per mit said guard to turn either way independently of said cap-screw and said wheel. and to permit the said wheel to turn without causing said guard to turn. 'lhc device is of such form and construction as to be adapted to lit any place on the shaft of a finisher which happens to be idle or vacant without the necessity of dismounting it. Shoe finishing machines usually have shafts on which two tools may be mounted. and some have mountings for four tools. This; device is adapted so as to be used on any oi these. The wheel 1 is reversible and works equally well running in either direction, when properly :taced. This is of advantage to both the right handed and left handed worlmian. The cap-screw can he unscrewed. and it and the guard taken oil and the wheel turned over. The guard is then replaced and the cap-screw fastened and tightened making the device again ready for use for the right or left handed workman owing to the way it turned. Both sides and the toe of the shoe sole may be worked on by the device without the necessity of making a change as above indicated and without stopping, or retarding the movement of the de vice or shaft, by simply turning the shoe. The guard protects the uppers ot' the shoes from being, injured from the teeth or wheel.

From the description, the accompanying one sheet drawing, the specification and claim, the advantages of construction, manutacture, application, and combination of parts of the invention will be apparent to those skilled in the art to which my invention pertains. l have entered into a dctailcd desmiption of the construction and the relative arrangement oi? the parts embra red in the present and prc'terred embodiment of my invention in order to impart a tall. clear and exact uzulerstamliirej ot the said cmln'idiment. It do not desire, however, to he understood as continingr iuyselt to the specific construction and relative arrange ment of the parts inasmuch as in the future practice (it the invention various changes and modifications may be made such as fall within the scope of my invention as defined by the appended claim, without departing from the principle oi the invention.

thievingthu-s descriljied the invention, what is claimed and desired to he obtained and secured by Letters Patent is:

in a stitch removing device, a body menr her having an inner end portion provided with a bore tor receiving therein the shaft of a finishing machine, set screws carried by said body member for securing the same to said shatt, said body member having an outer portion provided with a flange, a square portion projecting outwardly beyond the thing-c, and a round centrally disposed portion on said square portion and said flange. a cutting member having a square shaped opening fitted on said squared portion of said men'ibcr, a plurality oil claw shaped teeth on said cutting member, a guard having an openingadapted to he received on said round projecting portion and adapted to cover said teeth except at their outer end portions and a cap screw for retaining;- said guard in position, whereby the cap screw holds the guard and the cutting member on said body member but permits the guard member to revolve independently of the cutting member.
